呼伦贝尔草原植被覆盖度地面实测与遥感估算研究OACSTPCD
Ground Measurement and Remote-sensing Estimation of Grassland Vegetation Coverage on Hulunbeier Prairie
以内蒙古呼伦贝尔草原为研究区,共选择放牧区和非放牧区的47个观测样地,利用数码相机获取草地冠层照片,利用HLS彩色变换与RGB结合法及其他方法分别提取植被覆盖度.结果表明:本文发展的HLS彩色变换与RGB结合法提取的植被覆盖度的平均精度达85.85％,仅次于最大似然监督分类法.基于本文方法提取的实测点草地植被覆盖度与Landsat-5 TM影像计算的6种植被指数均有较好的正相关关系,其中与减小的比值植被指数(RSR)的相关性最高,从而建立了植被覆…查看全部>>
In this study, we chose forty -seven observation fields, including grazing regions and non -grazing regions on Hulunbeier prairie. A digital camera was used to get photos of the grass canopy in every experimental field. The method of combining HLS color transformation with RGB model proposed by the author, as well as other several methods were used respectively to extract the vegetation coverage from those digital photos. The results indicated that the metho…查看全部>>
